Abstract
The effect of redundant color coding on keeping-track performance was investigated, using symbols as the primary cue. Ss were assigned to one of four coding conditions: symbol color (SC), color symbol (CS), symbol only (S), or color only (C). Performance was measured on a task requiring S to monitor eight information channels, which were being updated randomly. Results indicated that the addition of a redundant color code did not yield a significant improvement in performance, as compared to performance on the component codes (i.e., the S and C groups).
